Summary: The study characterized the Turonian-Coniacian boundary in the Bohemian Cretaceous Basin using biostratigraphy, genetic sequence stratigraphy, and carbon isotope chemostratigraphy. It found faunal markers consistent with those in Germany and Poland, providing important new data for further study of the boundary interval. The study proposed that the T-C interval in the BCB complements sections in Germany and Poland, forming a broader region for defining the T-C boundary.

Summary: Numerous phosphate occurrences are found in the Bohemian Cretaceous Basin in the Czech Republic, consisting mainly of carbonate-fluorapatite and associated with various minerals. These phosphates are rich in organic matter and critical elements. The Turonian phosphate occurrences located at the southern margins of the basin are recommended for future exploration of marine sedimentary phosphorites.

Summary: The study analyzed nannofossil biostratigraphy in outcrop samples from the Cauvery Basin, determining the geological age to be from early Albian to late Turonian. The research found that some early biozones were applicable in both sections, while others were only partially applicable due to problematic markers. Further investigation is needed to fully understand the boundary intervals and paleobiogeographic affinities of the nannofossil assemblages in the region.

Summary: This study provides a paleoecological, systematical, and statistical evaluation of bivalve assemblages from the Pecinov Member in the Bohemian Cretaceous Basin, revealing the impact of the Ocean Anoxic Event (OAE2) at the Cenomanian-Turonian boundary on benthic organisms. The results show that prior to the positive shift of the 313Corg, the bivalve association is dominated by infaunal and semi-infaunal suspension feeders, with a near-absence of free-living epifaunal bivalves. In contrast, after the positive shift of the 313Corg, the assemblage suggests shallower depths and higher energy levels.

Summary: In the winter of 2018/19, the Yangtze-Huai River Basin in China experienced excessive and long-duration precipitation, similar to three other extreme pluvial winters in the past. The circulation patterns and tropical ocean states varied among these winters, with significant contributions from tropical sea surface temperature anomalies in the Indian Ocean and Pacific Ocean to the precipitation anomalies in the Yangtze-Huai River Basin.

Summary: The Achimov Formation in the West Siberian basin of Russia is a significant oil- and gas-bearing stratum with estimated reserves exceeding one billion tons. The formation is primarily composed of fine- to medium-grained sandstones interbedded with shale. Research indicates varying physical properties of reservoir rocks across different areas of the formation, with burial depth being a major controlling factor in reservoir quality.

Summary: This study investigates the exposure and influence of Variscan structures and metamorphic rocks in the Bohemian Massif and their impact on basin development in central Europe. Results reveal the presence of upper Paleozoic low-grade metasedimentary rocks and potential Variscan nappes approximately 65 km west of the Franconian Fault System (FFS). The location of post-Variscan late Carboniferous-Permian basins is controlled by the geometry of underlying Variscan shear zones.

Summary: This study provides age constraints on the Late Cretaceous Jiufotang Formation in the Jianchang Basin of western Liaoning, with fossil-bearing layers dated to around 122.0-118.9 million years ago. The findings contribute to a better understanding of the evolutionary history and temporal distribution of the Jehol Biota in northeastern China.

Summary: Contrary to the commonly accepted notion of lithosphere thinning, a thickening episode has been discovered in NE China. Lamprophyre dikes in the Tuquan Basin of the western Songliao Basin were studied and found to have formed during different periods, providing insight into the geodynamic evolution and magma sources from metasomatized lithospheric mantle.

Summary: This study documents the first record of a post-Mesozoic vampire squid from the Oligocene, indicating that vampire squids have been adapted to deep-sea, oxygen-depleted habitats since at least the Oligocene. The research suggests that the Cretaceous and early Cenozoic oxygen minimum zones triggered the deep-sea specialization of vampire squids.

Summary: This study reports a newly collected specimen of the enigmatic coleoid genus Longibelus from lower Turonian strata in Sakhalin, the Russian Far East. This is the first record of Late Cretaceous coleoid cephalopods from the island and suggests a potential habitat of neritic to mesopelagic zones over distal shelves and slopes.

Summary: This study systematically classified belemnites at the generic and species levels based on taxonomic work with rostra from the Stramberk locality in Northern Moravia, Czech Republic. A total of 23 species within 5 genera were recorded. The study provided important stratigraphical, palaeobiogeographical, and geological interpretations, and discussed the high diversity of belemnites in the sedimentary infills. The stratigraphic distribution of studied belemnites ranged from the ?latest Tithonian/Berriasian to Valanginian, ?Hauterivian and newly Barremian. The biogeographical position of the belemnite fauna from this region was found to belong to the Mediterranean Province.

Summary: This study describes ammonoid fossils from the Lower Muschelkalk of Rudersdorf, Brandenburg, Germany. The unique geographic location and high diversity of ammonoids in this area suggest that immigrants from the southeast and southwest met here. The study also revises the description of Beneckeia buchi and uses synchrotron data to analyze its early ontogeny.

Summary: Stable isotope data from bulk rock in the Jurassic-Cretaceous transition show stable values in many Tethyan carbonate sections, particularly those deposited in deeper-water marine conditions. The 813Ccarb curve at the J/K boundary interval does not provide significant value expressions for interregional correlation. However, a slight negative carbon isotopic excursion at the J/K boundary has been observed in well-calibrated sections, indicating a potential geochemical marker for stratigraphic correlation.

Summary: The paleoenvironmental conditions around the Jurassic-Cretaceous boundary in the Kurovice Quarry were studied using various evidence, including geochemical, magnetic, macrofaunal, microfaunal, and ichnologic data. Four recognizable ichnologic assemblages were identified, showing changes in both geochemistry and bioturbation activity. The geochemical variations indicate shifts in nutrient availability in the open ocean.

Summary: This study reports the first reptile remains found in the Upper Cretaceous marine strata of Siberia, including plesiosaurians, mosasaurids and turtles. These findings represent the northernmost occurrences of these reptile groups in the Cretaceous of Eurasia. The discovery of plesiosaurians suggests that the Arctic Polar Circle may have served as a birth and nursery area for these reptiles during the polar summer.

Summary: The scarcity of deep-sea macrobenthic body fossils is a methodological artifact due to the lack of deep-sea sedimentary records onshore. Our study reveals a continuous record of deep-sea Atelostomata since the late Early Cretaceous, indicating species changes primarily driven by in-situ evolution in the deep-sea.
